CASE tools:
It stands for “Computer-Aided Software Engineering”. It is a tool that helps engineers to develop and maintain software. It is used to automate tasks in Software Development Life Cycle.
Types:
The types of CASE tools are:
- Upper CASE tools: The tools that are used to automate early stages of Software Development Life Cycle are called as upper CASE tools.
- Lower CASE tools: The tools that are used to automate later stages of Software Development Life Cycle are called as lower CASE tools.
ICASE tools:
It stands for “Integrated Computer-Aided Software Engineering”. These tools are used to supply code generating capability. It gives a complete program based on diagrams that are produced by analysts. It is also capable to create tables for a

In a shopping cart, there are various items, which can either belong to the category of household items or electronic items. The following UML diagram illustrates the relationship between items, household items, and electronic items.
//Implementation Class
public class ShoppingCart{
public static void main(String[] args){
final int MAX_ITEM = 50;
Item cart = new Item[MAX_ITEM];
addItem(cart); // populate the item array
printItem(cart);
}
}
Considering that all the data definition classes and the implementation class are complete, which of the following Object-Oriented Programming (OOP) concepts do you need to use in the above context?
i) Polymorphism
ii) Method Overloading
iii) Method Overriding
iv) Dynamic Binding
v) Abstract Class
Explain, using course terminology, how you would use any of the above concepts to model the given scenario.
Answer this JAVA OOP question below:
An Employee has a name, employee ID, and department. An Employee object must be created with all its attributes. The UML diagram is provided below:
- name: String - employeeId: String - department: String
+ Employee(name: String, employeeId: String, department: String) + setName(name: String): void + setEmployeeId(employeeId: String): void + setDepartment(department: String): void + getName(): String + getEmployeeId(): String + getDepartment(): String + toString(): String
A faculty is an Employee with an additional field String field: rank
public class TestImplementation{
public static void main(String[] args){
Employee[] allEmployee = new Employee[100];
// create an employee object with name Tom Evan, employee ID 001 and department IST and store it in allEmployee
// create a faculty object with name Adam Scott, employee ID 002, department IST and rank Professor and store it in allEmployee } }
Please answer this JAVA OOP question that is given below:
An Employee has a name, employee ID, and department. An Employee object must be created with all its attributes. The UML diagram is provided below:
- name: String - employeeId: String - department: String
+ Employee(name: String, employeeId: String, department: String) + setName(name: String): void + setEmployeeId(employeeId: String): void + setDepartment(department: String): void + getName(): String + getEmployeeId(): String + getDepartment(): String + toString(): String
A faculty is an Employee with an additional field String field: rank
Assuming the Employee class is fully implemented, define a Professor class in Java with the following:
A toString() method that includes both the inherited attributes and the specialization
